Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the screening attentuation report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the ULTRA performance class, the focus is on MAXIMUM. Only highly developed shielding materials create our metrological requirements for the SFERICS® ultra classification. When every single dB counts!

Shielding materials and products are diverse. And extremely rich in essential technical details - a dramatic disadvantage for the layman. A small change in numbers in the umbrella report can ultimately mean a huge difference in measurement technology. EMF shielding classes create the common thread.
In the PRO performance class, the focus is on HIGH. Purely highly developed shielding materials create our technical requirement for a SFERICS® pro classification. When above-average shielding is the goal!

This LED TRICOLOR Pure-Z NEO with 9 watts produces a friendly natural light in three different light colors. The mode change takes place directly on the wall light switch and changes from warm white to daylight white to cool white).
The light produced is almost flicker-free. The light output corresponds to an 80 watts light bulb with a high color rendering index of over CRI 90. LED lamps in this quality class are state-of-the-art lighting technology and are highly recommendable from a building biology point of view.
Delivery time: approx. 1-3 working days | formerly energy class A+
Switchable 9 watt feel-good LED TRICOLOR Pure-Z NEO with E27 base. Three switchable light colors (warm white, daylight white, cool white) produce an almost flicker-free natural BIO LIGHT with high color rendering. Not dimmable.
This LED is a 3-in-1 illuminant with a near-natural BIO light i.e. with a high color rendering and almost “flicker-free” light.
The almost continuous spectrum of the emitted light is in the “warm white” mode close to that of incandescent or halogen lamps, but without the proportion of heat radiation (IR or infrared radiation). However, the two other operating modes “daylight white” and “cold white” make this LED technologically superior.
This color temperature switching technology was previously reserved mainly for commercial use due to price reasons. With this new development with reduced power, it has been possible to achieve an attractive price level. The reasons for this are private use, which is significantly lower in relation to commercial use, and the luminous intensity can also be lower.
The function for switching the light temperature remains the same, only the sequence of the individual light temperatures is adapted to the private household.
Warm white with a color temperature of 3,000 Kelvin
Daylight white with a color temperature of 4,000 Kelvin
Cold white with a color temperature of 6,500 Kelvin
The color change takes place directly at the light switch on the wall. If the light switch is operated within 3 seconds with Off/On, the LED TRICOLOR changes to the next color temperature. If the light remains off for longer than 3 seconds, it restarts at the first color temperature, warm white with 3,000 Kelvin – similar to the classic Edison light bulb or halogen light.
Details make the difference. This is especially true for LED’s!
The colour rendering index (Ra or CRI) describes the effect of light on the colour appearance of objects by comparison with daylight (not dependent on colour temperature). Incandescent lamps have a CRI of 100, these LEDs have a very good CRI of over 90.
The colour temperature is a measure of the respective colour impression of a light source. Warm light colours (warm white, 2700 K) have a low Kelvin number, cold light colours (cold white, 5000 K) a high one. This LED TRICOLOR is able to display 3 colour temperatures. Warm white, cold white and daylight white.
The light exit angle of almost 360º is very well suited for all applications where incandescent lamps were previously used.
LED lamps are made of a semiconductor and operated with integrated ballast. The resulting voltage produces a “light flicker” (pulsation). This pulsation could be reduced to a minimum (below 1 %) with the “filament” LED.
Electrosmog: The Pure-Z NEO LED has been designed to generate low technical fields comparable to those of a light bulb.
Consideration of the time of day: This is exactly where this TRICOLOR LED shows its full strength in private rooms. Daylight white and cold white contain a significantly higher blue component. This influences the human waking state and prevents the formation of melatonin, which is absolutely necessary for restful sleep. Later in the day, when reading in the evening, in the living room, at the bedside table or generally in the period before going to bed, switch the operating mode to warm white.

The new EU energy label since 2021
The new EU energy label for light sources, which will apply from September 1st, 2021, not only looks different, it is also based on new, stricter classification criteria. As a result, lamps and lights are classified in lower energy classes. However, nothing has changed in terms of the power consumption of the lamp.
Pay attention to healthy light when buying lamps!
Healthy light from a building biology point of view, is a light source modelled on the sun
without flickering, as close as possible to 0 Hz (Hertz)
a light spectrum/colour spectrum that is as close to nature as possible, without the predominantly much too high proportion of blue light in an LED, for example. This serves to protect the macula (prophylaxis against premature macular degeneration).
Day-adapted colour temperature, i.e. full spectrum during the day and warm light in the evening.
